Abstract

800,385. Steam generators combined with nuclear reactors. ROLLS-ROYCE, Ltd. Nov. 28, 1956 [Dec. 20, 1955], No. 36562/55. Class 123(2) [Also in Group XL(a)] A steam generator which may be employed with a conventional steam turbine marine power plant consists of a horizontally disposed generally cylindrical, pressure resisting casing 10 having a centre portion 11 to the respective ends of which are welded a hemispherical dome-shaped portion 15 and a cylindrical portion 13, both of smaller diameter than the centre portion. The casing is divided by internal tube plates 16, 17 into three chambers 18, 19, 20. Chamber 18 houses a watercooled nuclear reactor 22 in which is provided an outer annular space 24 through which coolant flows towards the end cover plate 21 of the chamber and a central return flow path 25 through the reactor core. The second chamber 19 houses a tube bank 27 which acts as a cooler for the reactor coolant circuit and as a heater for steam generation, the tube bank consisting of a number of sets of parallel tubes 30, each set extending between a pair of headers 28, 29 which are respectively connected into openings in the tube plates 16, 17. Some of the headers 28 communicate with the coolant inlet path 24 of the reactor and the remainder with the outlet path 25 therethrough. The third chamber 20 has provided in it a pair of axial flow pumps 33, 34 and internal partitioning 35 which defines a central suction space 36 and a surrounding delivery space 37 and which provides for a series flow of water through the pumps. The tubes 30 connected with the path 25 are connected through the associated headers 29 with the space 36 whilst the remaining tubes 30 connect the space 37 with the path 24 to complete the coolant circuit. The tubes 30 are each of shallow U - form to permit differential thermal expansion of the tubes and casing. The evaporator chamber 19 has a feedwater inlet 31 and an outlet 32 through which steam flows to a turbine 40, the turbine exhausting to the condenser 50 whence condensate returns to the chamber 19 through pumps 53, 54 and bled-steam heaters 51, 52. In the form shown, the water level in the chamber 19 is maintained just above the tube bank 27. In a modification, the chamber 19 is filled with water and the outlet 32 communicates with an external steam and water drum.
